<div class="block">This class implements simplex-based direct search optimization.

 <p>
  Direct search methods only use objective function values, they do
  not need derivatives and don't either try to compute approximation
  of the derivatives. According to a 1996 paper by Margaret H. Wright
  (<a href="http://cm.bell-labs.com/cm/cs/doc/96/4-02.ps.gz">Direct
  Search Methods: Once Scorned, Now Respectable</a>), they are used
  when either the computation of the derivative is impossible (noisy
  functions, unpredictable discontinuities) or difficult (complexity,
  computation cost). In the first cases, rather than an optimum, a
  <em>not too bad</em> point is desired. In the latter cases, an
  optimum is desired but cannot be reasonably found. In all cases
  direct search methods can be useful.
 </p>
 <p>
  Simplex-based direct search methods are based on comparison of
  the objective function values at the vertices of a simplex (which is a
  set of n+1 points in dimension n) that is updated by the algorithms
  steps.
 <p>
 <p>
  The <a href="../../../../../../org/apache/commons/math3/optimization/direct/SimplexOptimizer.html#setSimplex(org.apache.commons.math3.optimization.direct.AbstractSimplex)"><code>setSimplex</code></a> method <em>must</em>
  be called prior to calling the <code>optimize</code> method.
 </p>
 <p>
  Each call to <a href="../../../../../../org/apache/commons/math3/optimization/direct/BaseAbstractMultivariateOptimizer.html#optimize(int,%20FUNC,%20org.apache.commons.math3.optimization.GoalType,%20double[])"><code>optimize</code></a> will re-use the start configuration of the current simplex and
  move it such that its first vertex is at the provided start point of the
  optimization. If the <code>optimize</code> method is called to solve a different
  problem and the number of parameters change, the simplex must be
  re-initialized to one with the appropriate dimensions.
 </p>
 <p>
  Convergence is checked by providing the <em>worst</em> points of
  previous and current simplex to the convergence checker, not the best
  ones.
 </p>
 <p>
 This simplex optimizer implementation does not directly support constrained
 optimization with simple bounds, so for such optimizations, either a more
 dedicated method must be used like <a href="../../../../../../org/apache/commons/math3/optimization/direct/CMAESOptimizer.html" title="class in org.apache.commons.math3.optimization.direct"><code>CMAESOptimizer</code></a> or <a href="../../../../../../org/apache/commons/math3/optimization/direct/BOBYQAOptimizer.html" title="class in org.apache.commons.math3.optimization.direct"><code>BOBYQAOptimizer</code></a>, or the optimized method must be wrapped in an adapter like
 <a href="../../../../../../org/apache/commons/math3/optimization/direct/MultivariateFunctionMappingAdapter.html" title="class in org.apache.commons.math3.optimization.direct"><code>MultivariateFunctionMappingAdapter</code></a> or <a href="../../../../../../org/apache/commons/math3/optimization/direct/MultivariateFunctionPenaltyAdapter.html" title="class in org.apache.commons.math3.optimization.direct"><code>MultivariateFunctionPenaltyAdapter</code></a>.
